sists in certain-novel features of construe# tion as hereinafter setforth..

ln the drawings:

is 'a crow-section lthrough the Figure l uelizer;

Figure 2 isa longitudinal section therethrough;

Figure 3 1s a horizontal section.

ln the construction shown the fuelizer is formed as a unit which isinsertable between the carburetor and the inlet manifold of an internalcombustion engine. said unit comprising a casing A having therein aconduit section B, whichiorms a portion of the intake with a chambersurroundingl said conduit section and an outer jacket D surrounding saidchamber. The combustible mixture is drawn into the fuelizer from thecarburetor and as shown is rst drawn through a y hollow throttle valveE, passing through the hollow stem F thereof into a port G which is inregistration with a port H in the fuelizer in the chamber formed by theouteriacket thereof. From this chamberthe combustible mixture passesaround the iaclret and ythrough a valve controlled port l into thechamber C, where it is ignited by a sparlr'plug J and the flame andproducts of combustion pass around the conduit section B and Hna-ily.after the extinguishing of the lame. into the intake.

With thev construction as thus far described. it is vital that the iiameheroin pletely extinguished 'before passage into the intake.l asotherwise it will explode the mixture therein. l' have thereforeprovided a construction which' eectually guards against any passage ofthe Flame and which follows: K is a screw-threaded plug is as whichengages a correspondingly threaded opening throughy lthe outer and inneriaclzets communicating with the chamber C. ln alignment with thisaperture there is an aperture lL in the wall of the conduit section B,through which the products of combusinner tube N is threaded at itsinner end for engagement with the aperture L, which is correspondinglythreaded, and the arrangement is such that by screwing in the plug Kengagement is also made-between the inner tube N and the' wall of theconduit B. The inner tube is further provided near its upper end with aplurality of apertures N for establishing communication between itsinterior and the space within the outer tube M,' while the latter tubeis provided at its opposite or inner end with'a plurality of aperturesM, establishing communication between the chamber C and the spacebetween the tubes. Thus the suction of the intake will draw the Hanne'and products of combustion from the chamber C,

through the apertures VM" into the space between the tubes and thenthrough the apertures N7 into the inner tube and into the intaire'. Inpassing through these 'apertures the temperature is lowered and as theinner tube is shielded from direct contact with the flame in the chamberC, it will be at suiiiciently low temperature to insure the eX-tinguishing of any flame which vpasses through the apertures in theouter tube be- 'fore it can pass through the apertures in the innertube. It will also be noted that as both inner and outer tubes areattached to the plug K, the heat will be rapidlyA conducted outward,while the ungnited combustible mixture in the outer `iacket contactingwith said plug will have a cooling eect thereon. As a further safeguard.there is arranged within the chamber C a baie O which passes up to aboutthe longitudinal center of the tubes M' and N and then across.v

being apertured Jfor the passage of said tubes. This will compel theHaine in the chamber C to nass aroundv in the direction indicated by thearrows and will further lower the temperature before the gaseousproducts reach the intalxe.

When a Juelizer is used in cold weather, there is always a certainamount of condensation in the outer jacket. due to the contact ont theliquid fuel with the outer cold walls. This condensation will drop tothe lower portion of the passage when the fuelizer is not in use and ifit is subsequently thrown into operation, the quantity of liquid fuel inthe passage will form an overrich mixture, interfering with the ignitionforms the lowermost point in the outer passagemQJ is a second plugengaging an aperture in the wall separating the outer passage from theinner chamber C and this plug has a restricted aperture Q l therethroughand through a downward extension Q2 of the plug into the well or sump P.

VWith this-construction there will always be a higher vacuum in theinner chamber C than in the outer passage, and consequently, any liquidfuel which collects in the sump P will be drawn up through the passage Qand into the bottom of the chamber C.

Here it will be in the path of the flame ignited by the spark plug J andwill be swept along with the flame and products of combustion passingfinally into the intake. Ys;Eer-thermostatically controlling theoperation of the fuelizer, the port I is controlled by a sleeve valve R,which in turn is actuated by a thermostat S. This con` struction doesnot, however, form any part of the present invention.

What I claim as my invention is:

1. In a fuelizer, the combination with a casing having a conduit sectiontherethrough forming a portion of the engine intake, and a surroundingchamber constituting a combustion chamber, o-f means for preventingpassage of flame from said combustion chamber into said intake comrisingconcentric inner and outer tubes having perforations therein out ofregistration with each other, the outer tube forming a shield for theinner tube, and means for conducting away the heat fromI the inner tube.

2.In a fuelizer, the combination with a casing having a conduit sectiontherethrough forming a portion of the engine intake, and a surroundingchamber constituting a combustion chamber, of means for preventing thepassage of flame from said combustion chamber into said intakecomprising a plug engaging an aperture through the outer Wall of thecasing, concentric tubes secured to said plug and extending inwardtherefrom, the inner tube engaging an aperture in the Wall of theintake, said tubes having perforations therein out of registration andat opposite ends thereof, whereby the products of combustion passingthrough the outer tube must pass through apertures in a portion of theinner tube shielded by said outer tube.

3. In a fuelizer, the combination with a casing having a conduit sectiontherethrough forming a portion of the engine intake and a surroundingchamber constituting a combustion chamber, of means forv preventing thepassage Aof-lame from said combustion chamber into said intake,comprising a plug engaging an aperture in the outer Wall of the casing,concentric tubes carried by said plug, the inner tube engaging anaperture in the wall of the intake and said tubes having perforationstherein out of registration and at opposite ends thereof, and a baiiiefor protecting the perforated portion of the outertube from directimpingement of the ame, said inner tube being protected by said outertube.
